| Popis: | The aim of the study was to assess the effectiveness of infrared spectroscopy for verification of pulmonary embolism (PE) and a number of similar diseases. Materials and Methods. Infrared spectroscopy was used to investigate blood serum of 19 healthy volunteers and 30 patients with intraoperatively confirmed PE as well as with chronic obstructive pulmonary disease (COPD) (n=10), pneumonia (n=10), tuberculosis (n=10), lung abscess (n=10) and lung cancer (n=10), acute disorder of cerebral circulation (ADCC) (n=10), ischemic heart disease (IHD) (n=10). Peak height ratios of absorption band were taken as diagnostic parameters (cm–1/сm–1): P1 — 1160/1165; P2 — 1165/1070; P3 — 1165/1150; P4 — 1165/1050; P5 — 1100/1050; P6 — 1025/1165. These parameters of IR spectrum are significant for the given nosology. Results. The calculated indicators have demonstrated statistically significant difference of IR spectra parameters for the studied nosologies (p |
